It's here! The final show of the final series of Big Brother. We're in for a long night, no doubt with plenty of tears, reminiscing and nostalgia as we look back on ten years of the show and crown our Ultimate Big Brother winner.

Whether you've followed every series, dipped in and out over the years or believe Big Brother is responsible for most of society's ills and thus hate it even though you've never watched it, you can't deny it's been a Channel 4 institution. Some bits have been brilliant (everything before series 4) and some bits not so much (Celebrity Hijack, anyone?).

Either way, we've got just one night to go, so add your comments below and let's make a night of it. See you at 7.30pm!

7.17pm: Right, are we all ready? I have fortifying snacks and soft drinks at the ready - alas no BB drinking games for me, I have to drive later. But feel free to indulge without me. May I recommend a slug every time Davina cries, and down in one whenever someone says the words 'journey' or 'rollercoaster'.

Anyone who makes it through to 11.30pm with me wins my eternal respect and gratitude. Terms and conditions may apply.

7.27pm: And we're off! Blimey, Davina's not wearing black! Instead, she has dressed as one of the less popular Quality Street options. Bad, bad idea.

7.29pm: A few stats for you - there have been 267 housemates in 19 series. About 20 of them have been utterly brilliant, the rest have been weird, unhinged, creepy or just wallpaper.

Tonight we'll be reliving all the best bits, looking behind the scenes, watching Dermot have supper with all the best housemates, seeing all Davina's favourite moments and finally crowning an ultimate winner with tears and hankie-waving.

I'll be liveblogging the whole lot. Who's with me?

7.35pm: So I know it's got slightly lost in all the last-hurrah nostalgia, but who should win tonight? Part of me thinks Nick just because closing the BB loop in such a tidy fashion pleases me, but I think it has to be Brian, purely because he remains my favourite BB housemate of all time. Except I also love Victor. Oh choices, choices.

7.39pm: God, I'm welling up already. I know BB has had its ups and downs (all-time low: Kinga), but there is much to look back on that has been brilliant television. It's not everyone's cup of tea, but I am genuinely going to miss it. Must. Not. Blub.

7.46pm: Davina is reminding us of some favourite BB catchphrases. "I could kill somebody with these two fingers" - ha, had forgotten that one from Lisa in BB4. Don't worry if you can't remember it, it's the series where we had to endure Federico and no-one watched after John Tickle left. It's also the series where I got to do a tour of the camera run AND Dermot kissed me on the cheek. Happy days.

Voiceover man Marcus is conducting a funeral for Big Brother. All the housemates make a short speech - Victor manages to get the phrase "hot lesbian action" into his, which sort of spoils the moment. They are playing Barber's Adagio For Strings. Is anyone else waiting for the DJ Tiesto version to kick in?

7.57pm: Right, nearly time to kick someone out. I'm thinking Preston to go first. It's the final ever recap, and Brian is dancing to Kylie on the sofa. Watching his reaction to being followed around by all the housemates over the last few days has been hilarious - sometimes the simple plans to mess with someone's head are the best.

Christ, they are playing James Blunt's "Goodbye My Lover". Of all the cruel, sadistic tasks Big Brother has set the housemates, making them endure three minutes of this musical excrement is truly harsh. I hope they get extra beer for passing. Preston does a runner into the garden. I'm surprised he's not shouldering the fire escape.

8.04pm: We've gone backstage to see how the show gets put together. What is Marcus Bentley going to DO with himself after tonight? Has anyone found him a new job? I worry about these things.

I don't want to see who the Tree of Temptation really is. I like to think it's an actual chest of drawers with a disembodied voice and a serious attitude. The magic is gone if it's got real arms and legs.

This is actually very interesting. They should have played this all those times Tim from BB3 was in the diary room banging on about his contact lenses and asking Big Brother to 'comprende?. Or every time Rex appeared on screen.

8.11pm: We have learned that Davina eats lentil soup before going on stage, whilst having her hair and makeup done. Truly it is the tiny details that matter. Can I retrospectively include the word 'emotional' into the drinking game? Clearly I'm not taking part, but you guys can drink my share.

And the first housemate out is....ULRIKA!!!. She was lovely, but clearly never going to win.

8.19pm: It's time for Ulrika's interview. I quite like Ulrika, she's like everyone's mum. She looks like she needs a jolly good feeding up though. Why is there so much hate in the comment box? Did I miss something?

My daughter has offered to make popcorn. This is excellent news.

8.24pm: Forgive me if I don't provide a blow-by-blow commentary of the interviews, they're invariably incredibly dull. I have one ear open for anything noteworthy.

She loved everyone, and wants Brian to win. See? Nothing to see here.

8.33pm: Finishing 6th is....PRESTON. How long before Davina shamelessly asks him if he still loves Chantelle in a clothes-removing way?

Blimey, who knew Preston looked so good with his shirt off? A not-very-ordinary boy at all, as it turns out.

8.37pm: Yeah, she barely got past the pleasantries. He clearly still cares about Chantelle, and now is being subjected to all the "I still love him" crying she's been doing over the last couple of weeks.

Part of me wants them to get back together, but part of me thinks it would probably be a disaster. It's all very sweet though, I find myself genuinely hoping they find a solution that works for them, and that this experience makes them closer in some way. As someone who is currently liveblogging from her ex-husband's front room while he's out on a date, I respect the concept of post-divorce frendship.

Christ, listen to me. I haven't even been drinking.

8.44pm: Blimey, whilst I've been wittering on with my special brand of marriage guidance, they've evicted NICK. I'm glad he went back in, he's been good value and seems to be a really nice guy. I suspect he's very glad to shed the 'nasty' tag he's been lugging around for the past ten years. Still not sure I can ever entirely forgive him for the dead wife story though.

Sorry, but Lionel Richie advertising crisps is just WRONG.

8.50pm: Nick's best bits - him being nice, and having fun, and clearly getting his confidence back a little bit. See, how can anyone say this show is crap? THIS is why it's brilliant.

Blythy in the comment box has just read my mind - what would it be like to watch the original series again? I'd love to see it, a very different kind of Big Brother I imagine. I can remember more of the housemates' names from BB1 than I can from last year.

8.59pm: It's time for fourth place - Davina is apologising for all the swearing. Oh, can we not just let it go for one night? No one really cares.

Fourth is....VICTOR!!! Which means it HAS to be Brian for the win, although there is plenty of love in the crowd for Nikki. I'm just not sure she's mentally equipped, a win could tip her over the edge from mildly bonkers into totally hatstand.

I love Victor. One of my top housemates EVER.

9.06pm: Victor and Michelle in the bedsit was hilarious - what I love about Victor is he's all dick-waving and Alpha Male on the surface, but underneath he seems to be a genuinely sensitive guy. And he's very, very funny. Can't believe he came 7th last time. Great value housemate, I could watch him for weeks.

9.14pm: Wow, we've been at this for nearly two hours already - we're nearly HALF WAY, people! Doesn't time fly when you're having fun?

It's time for Jade's story. I appear to be getting snuffly.

9.18pm: Jade's story is amazing and tragic in equal measure. It's very sad to watch, but then of course we know how it's going to end.

So very sad. The biggest star this show ever made, but just a girl at the end of the day.

9.27pm: And that's it for the first part of the show - Brian, Nikki and Chantelle are in the final three in the sideshow that is the Ultimate Big Brother winner. Up next is Dermot's Last supper, which I'm very much looking forward to as I still harbour a giant crush. The continuity guy has just promised nudity. Please let it be Dermot. I'm loving this evening's show, is everyone still with me?

9.31pm: Dermot's gathered together eleven of his favourite housemates, out of those who were available and could get a night off from KFC. They are eating Marjorie the chicken from Big Brother 1.

His guest list is: Cameron, Alex, Narinda, Marco, Craig, Anthony, Pete, Brian, Rex, Bea and Ben. For some people, the dinner party from hell. For others, a great night in. Only two girls, though? And one of them NARINDER? She was nothing without Brian.

9.35pm: I met Craig once. I was working at the BBC Good Homes Show and he came onto our stand to ask if he could have some free stuff in exchange for allowing us to take his photo. I shan't repeat the words I used to send him packing.

Ah, Alex from BB3. Another one of my all-time favourite housemates. And Cameron from BB4! That was the series where nothing happened, and everyone was nice. But it did have John Tickle, who I once met at a wedding. He was lovely.

Marco now has hair and is quite good looking, which I am finding both confusing and unnerving. BB5 had Michelle boffing Stu under the table and the joyous Nadia, but also had Fight Night, which was brilliant on so many levels, even though I do remember watching it through my fingers. It could be argued that this is the point at which Big Brother began to eat itself.

9.45pm: Ahh, BB6. Craig's deeply sinister crush on Anthony (who has now got guns you could use to bridge the Tyne), Makosi getting jiggled in the jacuzzi (but not having sex, apparently). They don't mention Kinga. I am glad about this.

BB7 was all about Pete and Nikki, possibly the most unlikely match ever. They lasted two weeks, apparently. And of course Glyn, who also makes my top five. BB8 gave us Brian, who is not the sharpest tool in the box by quite a long way. Watching him on Come Dine With Me last week was terrifying.

BB8 blessed us with Rex, who was possibly one of the most odious individuals ever to feature on this show; everything about him made me bilious. BB9 is represented at Dermot's table by Bea, which is a shame because The Irrepressible Dark Horse Marcus and Halfwit were far more entertaining. How did Sophie win that show?

Ben is there from BB10, who I loved. Was actually quite gutted when he left this series.

A nice little recap, I enjoyed that. Even the wilderness years had some good bits. Apart from BB4, that was just dull.

10.01pm: And now it's time for Davina's Big Send Off. She's not everyone's cup of tea, but she definitely wins points for dedication to the Big Brother cause.

10.05pm: Ah, one of my favourite Big Brother moments ever - Mario saying "Mikey's got a disability - open your eyes, people". Hilarious. What the hell has happened to Lisa? She appears to have melted. Mario probably wants to give her a health and safety assessment. He might also want to get his hair checked out for fire risk.

Can someone please explain the point of George Lamb?

10.12pm: Luke and Bex are no longer loved up. In fact they appear to hate each other. Luke still looks like Pob.

10.17pm: Oh Christ, they've dragged Westwood out of his cave to show Davina in her bikini. Why? Why?

Davina has picked her sexiest housemate - Stuart from BB9. He was indeed several miles beyond hot, but somewhat dead behind the eyes.

Davina has confessed that Brian is her favourite ever housemate. She's previously said Nadia, but she's been ousted in favour of Brian after his UBB performance. I hope someone's keeping a proper eye on Nadia, and that she is OK. I don't imagine this bombshell will have helped.

Eek! Pete Burns has rocked up to sing "You Spin Me Round" to Davina. She is dancing in a mildly uncomfortable manner, like your drunken auntie at a wedding. You know in Toy Story when Mr Potato Head is put back together with all his face bits in the wrong holes? Always makes me think of Pete Burns.

10.28pm: We're into the FINAL HOUR, PEOPLE!! And I'm still having fun. Please stick with me, we're nearly there.

Davina is now wearing some kind of funeral outfit, but just looks a bit like a Victorian beekeper. She's reciting some bastardised version of Auden that isn't really working. Come on, this show has been brillliant so far, don't milk it now.

10.33pm: In third place is CHANTELLE. Let's assume the same interview as Preston, but with the names swapped round. Feel free to pop the kettle on.

So final two are Brian and Nikki - really could go either way. Both of them want it so much you can smell it. I'd like to see Brian win, but in lots of ways Nikki would be a worthy winner. She's certainly a housemate we'll all remember.

10.45pm: Ah, Chantelle. How can you not love her? She's just sweet, and vulnerable, and messed up. Preston is a good man, I think, just maybe not the right one for her. Nice to know that there's was genuine love affair, though.

Blimey, that was quick. Get off Chantelle, we're down to the final two. It's time to announce the Ultimate Big Brother winner! Nikki looks like she's about to pass out.

And it's....BRIAN!!!. Well of course it is, how could it have been anyone else? Poor Nikki, so close and yet so far.

10.51pm: I would say "Nikki, the 1960s called and they'd like their outfit back", but she's actually looking amazing. She's still deeply annoying though, and definitely borderline unhinged. I do wonder if she'll ever grow up.

10.59pm: I've never been able to make my mind up about Nikki. She is clearly vulnerable and often sweet and loving, but also incredibly stroppy, self-obsessed and awful. The whinging makes my ears hurt, yet I still want to give her a hug. It's very confusing.

11.03pm: I'm starting to get a bit emotional. I can't even begin to count how many hours I've invested in this show. What the hell are we going to do next summer?

Brian is genuinely sobbing. This means so much to him. I love him to bits.

11.06pm: Out comes Brian, to a storm of fireworks. I hope the Elstree locals have got their dogs inside. @Janinegibson votes for blowing up the house, which would of course be BRILLIANT. Brian could push the plungey thing.

11.12pm: A fitting winner, I think. He seems to be a genuinely good guy, consistently a team player, and arguably the funniest housemate ever to grace the Big Brother house. A natural comedian, equalled only by Victor for giving me big proper belly laughs.

11.17pm: He's been on a really journey, has Brian, and he could have turned in to a right twit but apparently hasn't. A fitting end, I think.

Or maybe this is the fitting end - a version of "Time to Say Goodbye" evidently done with the budget C4 now has kicking around and mimed by previous housemates, all of whom are looking outstanding. Good call on the miming, by the way, singing would have been dreadful.

The production team have made a film for Davina. She's about to fall apart, I think. It makes you realise how much Davina has been integral to this show, and her genuine commitment for ten years. I don't think many presenters can say that, and her love for Big Brother is without question. She makes my teeth grind sometimes, but you can't help but admire her. Go Davina.

11.28pm: And that's actually, really it from me. Thank you everyone who has taken part in the BB liveblogs; they started way back in 2006, pioneered by the brilliant Anna Pickard and Janine Gibson - in fact the very first comment I ever put on a Guardian blog was during CBB in 2007. A year later I was invited to join the liveblog team, and it has been an absolute joy and a privilege. I'll miss the show, but I'll miss the liveblogs more. They are nothing without your brilliant comments, so thank you very much, and have a great weekend!
